- Linux version: Arch Linux
- Kernel Version: 7.2.11-arch1-1
- GPU Model: not relevant, reproduces even with --no-video
- Mesa/GPU Driver Version: Mesa 26.2.5-1, but not relevant
- Window Manager and Version: no window manager or compositor, the environment can be reproduced with kmscon-launch-gui for example
- Source of mpv: pacman/extra
evdev is present, consider the environment TTY-stream deficient.
Reproduction Steps
When run barebones in pure TTY-stream deficient DRM envrionments (e.g. when run via kmscon-launch-gui, the standard and only way of running another "GUI" program in kmscon) mpv doesn't react to keyboard and pointer/click events and it's impossible even to quit or close it normally.
Expected Behavior
I expected mpv to react to at least keyboard events and perform the bound actions like seek, speed, quit, etc, as it does when, e.g., run without kmscon-launch-gui (in that case with --no-video option obviously).
Actual Behavior
There was no reaction. Had to kill the process.

No response
I carefully read all instruction and confirm that I did the following:
- I tested and confirmed that the issue exists with the latest release version or newer.
- I provided all required information including system and mpv version.
- I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of
--log-file=output.txt. - I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
- I attached the full, untruncated log file.
- I attached the backtrace in the case of a crash.

Assuming your log isn't incomplete, mpv didn't receive any inputs in those logs. I don't think this is a mpv bug. mpv works perfectly fine in tty, see what kmscon is doing.
mplevako commentedon Oct 29, 2026
As I see it,
kmscon-launch-guitemporarily releases its exclusive GPU/DRM control so thatmpvcan grab it. Technically there's nokmsconafter that point andmpvruns "alone".Not sure, but as I understood
mpvexpects key presses to arrive throughstdinandkmsconprovides it andmpvworks properly (as I mentioned in the Expected Behavious para.), which is irrelevant as the main problem shows in the specific pure DRM mode, the only mode possible to get any video output frommpv, where nostdinis available.CounterPillow commentedon Oct 29, 2026
Launching from a classic Linux kernel VT will absolutely make mpv's DRM video output/video context give you a stdin.

I run

kmscon doesn't forward keyboard input to the terminal while it's backgrounded, and it's neither an X server nor a Wayland compositor. So it doesn't support any of the ways mpv can understand input.
Adding a libinput backend to an app like mpv is silly, so this probably won't ever work without changes to kmscon or running mpv inside a compositor
You can follow kmscon/kmscon#406 (comment)
mplevako commentedon Oct 29, 2026
Why is it silly?
llyyr commentedon Oct 29, 2026
It adds considerable code to mpv for something that only matters for kmscon. mpv is well served by using Wayland/X protocols for input, and /dev/tty directly when running without them.
You can simply run mpv inside a Wayland compositor.
mplevako commentedon Oct 29, 2026
Doesn't seem like a pure DRM environment, does it?
CounterPillow commentedon Oct 29, 2026
llyyr didn't say it was. kmscon is also not a pure DRM environment; specifically, it eats your input here by backgrounding itself but not giving mpv a proper TTY.
llyyr commentedon Oct 29, 2026
no it's not, and neither is kmscon. mpv works perfectly well inside a pure DRM environment, if it doesn't feel free to report a bug.
There's nothing much else to add to this issue, if you want things to work then it's a bug report for kmscon, or a feature request for mpv. Maybe someone will come along to add and maintain a libinput backend in mpv for this use case if they use it often enough.
mplevako commentedon Oct 29, 2026
The now default VT console in Fedora and Gnome OS?
CounterPillow commentedon Oct 29, 2026
Use case for using a broken VT that relies on arbitrary sleeps to not race drm master release?
llyyr commentedon Oct 29, 2026
Report a bug for Fedora and Gnome OS for defaulting to a broken application? Not sure what you want us to do here.
Most likely this is something that was overlooked by them when they made kmscon the default, or deemed not an important enough use case. In either case, you'll have to report the bug to them to get some kind of resolution to your problem, not to mpv.

Again: DRM has no concept of input.
CounterPillow commentedon Oct 29, 2026
@na-na-hi Are keymaps handled by libinput, or will mpv need to grow keymap handling?
kmscon already has handling for keymaps, which means they could provide a proper terminal to applications it launches, which would sidestep this bug in kmscon's emulation of Linux VTs entirely.

Sure, feel free to use it through the terminal or

Sorry, didn't pay attention to that option, but anyhow, having read about it now, I cannot understand how it can help handle keypress events. Could you please elaborate.
[-]No reaction to keyboard events when run barebones in pure DRM envrionments[/-][+]No reaction to keyboard and mouse events when run barebones in pure DRM envrionments[/+]CounterPillow commentedon Oct 29, 2026
It's meant for providing non-terminal non-display-protocol input, such as when you're running with no terminal attached and without X11 or Wayland, using a generic IPC. Your complaint has nothing to do with DRM, and "but mpv has a concept of input" is not a rebuttal to this being unrelated to DRM. What you ran into is that kmscon does not properly emulate VTs, what you want is either for mpv to use libinput or for kmscon to emulate the terminal properly, what you're claiming is that this is mpv not supporting input in a DRM context. mpv supports input in a DRM context, just not for your specific use case, which is kmscon launching mpv without the terminal attached to stdin.
mplevako commentedon Oct 29, 2026
First of all I want you to finally stop fixating on
kmscon. I don't know why there're issues with this IMHO easiest way of reproducing the problem, but, again, I also have nothing against using other options of puttingmpvinside a raw absolutely/totaly/completeley 100% kmscon-free DRM context. I don't know, do you, for example, have any issues with tinkering withsystemdandsystemd-runto achieve that?Second, is it possible to make
mpvreact to mouse events so that it can be closed by clicking the 🗙?CounterPillow commentedon Oct 29, 2026
I will not stop focusing on kmscon. I know you can run mpv without a terminal input in other ways. That does not change that this is fundamentally either a feature request to mpv to add a libinput backend, or a bug report to kmscon to fix its VT emulation, but it's not a bug in mpv's DRM support.

Can you create PR with such change? Thanks.

It is handled similar to wayland, using xkbcommon.
Done.

@Dudemanguy Whenever you have a moment, could you please remove the
down-upstreammislabelling, the issue has already accumulated more than enough confusion and misinterpretation without it.avih commentedon Oct 30, 2026
@mplevako please stop adding comments.
We all undrstand the issue, it's not an mpv issue, and many of your comments don't add new info.
So please take a breath before you comment, and if you think we could live without it, then please don't comment.
